10. Peanuts
Here’s something that poses no risk to most people (unless they choke on one) but can be absolutely lethal for people that are allergic. Peanuts are one of the most common food allergies known to man, and here’s what makes it even scarier: A peanut allergy can develop at any time during your life – even if you never had a single sign of it before! That’s why it is best to see your doctor if you start showing even subtle signs of a peanut allergy such as experiencing itching around your mouth after eating them.
